Difficulty level: Tough
Reference: The Hindu
Why the question:
Recent satellite images have shown a pair of cyclones in the Indian Ocean region, one in the northern hemisphere and one in the southern hemisphere. Named cyclone Asani and cyclone Karim respectively, these are twin cyclones originating in the same longitude and now drifting apart.
Key Demand of the question:
To write about twin cyclones and their process of formation.
Explain – Clarify the topic by giving a detailed account as to how and why it occurred, or what is the context. You must be defining key terms wherever appropriate and substantiate with relevant associated facts.
Structure of the answer:
Start by defining twin cyclones.
First, write about the various factors leading to the formation of twin cyclones – interplay of the wind and the monsoon system, role of equatorial Rossby waves, latent heat of evaporation and general conditions conducive for the formation of the cyclones.
Conclude by mentioning the impact of twin cyclones as conclusion.
